In recent years, animal products, as an important source of human daily diet and consumer goods, have increasingly faced the risk of microplastic contamination. These microplastics can enter the human body through food consumption or the use of daily products, posing a threat to health. However, there is currently a lack of comprehensive reviews on the impact of microplastic contamination in animal products on human health. This review begins with the sources, migration, and accumulation mechanisms of microplastics, systematically elaborates on the routes through which microplastics enter the human body via animal products and their harmful effects on the body, and summarizes the detection and elimination technologies for microplastics in the environment to ensure the safety of animal products and human health. In summary, microplastics can enter animals through ingestion, gas exchange, and contact, and can remain in animal products, posing potential risks to the human respiratory, digestive, and immune systems. Although existing detection and removal technologies for microplastics have played a role in ensuring the safety of animal products, further optimization is needed to develop more efficient and environmentally friendly methods. In the future, efforts should be strengthened to research pollution prevention and purification technologies for microplastics, reduce their residues in animal products, and thereby effectively safeguard food safety and public health.</div></div>","PeriodicalId":439,"journal":{"name":"Trends in Analytical Chemistry","volume":"185 ","pages":"Article 118187"},"PeriodicalIF":11.8,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143379420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study reviews close to 90 relevant publications. Seventy studies were selected using ResNetBot, a tool designed to identify key works based on their significance to other studies matching the search criteria. The selection focused on global occurrence of microplastics within agricultural landscapes, emphasizing their distribution, origins, concentrations, morphology, color, polymer types, dimensions, vertical distribution, and the implications of land use. Furthermore, this study included predominant methodologies for extracting, identifying, and characterizing microplastics. Plastic mulch films represent the primary source of input, accompanied by sewage sludge, biosolids, irrigation water (notably wastewater), atmospheric deposition, and polymer-coated fertilizers, among others. Concentrations exhibit considerable variability, ranging from a few particles/kg in low-input regions to exceeding 80,000 particles/kg in areas subjected to prolonged mulching practices. Polyethylene and polypropylene are the most frequently encountered polymers, while fragments, fibers, and films are predominant forms, with films strongly linked to mulching and fibers typically associated with biosolid applications. Transparent/white and black particles are predominant, reflecting the materials commonly utilized in film applications. Microplastic concentrations generally decrease with soil depth; however, smaller particles penetrate deeper soil layers. Intensive agricultural practices demonstrate significantly elevated microplastic loads in comparison to less intensive or natural ecosystems. Density separation methods (commonly utilizing NaCl) followed by digestion processes (often employing H₂O₂) are standard practices for isolating microplastics while spectroscopic methodologies (including FTIR/μ-FTIR and Raman spectroscopy) are essential for verifying polymer composition and ensuring precise identification.</div></div>","PeriodicalId":439,"journal":{"name":"Trends in Analytical Chemistry","volume":"185 ","pages":"Article 118176"},"PeriodicalIF":11.8,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143379419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
